Yeah, I know it is the entry called board body in the view menu. I
just tried rev 5005, here the board body is _not_ transparent, even if
the solder mask is hidden.

I do see the string "Transform", but it does not look like a section
block to my, but now I am not familiar with VRML files.

The head looks like:
#VRML V2.0 utf8

DEF STL_object Transform {
  children [
    Shape {
      appearance Appearance {

          transparency 0.0
          shininess 0.0
        }
      }
      geometry IndexedFaceSet {

          -7.800000190734863 -1.3086742162704468 0.20000000298023224,
